NMN vs CoQ10

for energy / fatigue

Stronger evidence: CoQ10

Stronger effect: unknown

Safety: No notable interactions recorded for either.

For energy / fatigue, CoQ10 has the stronger evidence grade.

not well studied very-low certainty

not adequately studied for fatigue/energy outcomes in humans

grade C low certainty

limited evidence for general fatigue; clearer in specific conditions (e.g., statin myalgia, mitochondrial disorders)

100–200 mg/day, adults
